To determine the average rainfall deficit for Washington in 1934, you would typically need data from the map referenced in your question, which I do not have access to. However, based on historical data, the state of Washington was notably affected by drought conditions during that year.
Many records indicate that parts of Washington experienced significant shortages in rainfall, but specific average deficits may vary by region. If you have access to numerical data or specific legend information from the map, you could estimate the average by looking at the relevant sections that represent Washington's rainfall anomalies.
Based on this historical context, if you're required to choose an option based on your own research or the map's information:
- if numbers are close to 3.0-4.0 inches below normal, then you would select that option.
- if it is around 4.0 inches, you would select that.
- if it’s closer to 4.0-5.0, then select that range.
- if it is about 5.0 inches, select this option.
Without the exact visual reference or accompanying data, I can't give a definitive average, but historically, many areas reported deficits ranging around 4 to 5 inches. If you have access to the specific details or data points, you would be able to make a more accurate assessment.
